Safety Precautions 1. Do not exceed temperature or pressure rating of strainer assembly. 2. Do not loosen or remove any clamps while the strainer is under pressure. 3. Lockout supply pump(s) and other equipment in-line with the strainer during cleaning to prevent accidental operation when strainer is open. 4. Use protective gloves when removing strainer element and clearing debris from element. 5. Use only Sani-Matic replacement parts.
Installation and Operation
Figure 1: ALB Strainer Flow (Side-Inlet)
Angle-Line Basket Strainers are designed for flow in one direction, resulting in the soils being collected on the inside of the strainer basket. Angle-Line Basket Strainers are supplied only as ‘Side-Inlet’ flow, as indicated by the arrow on the side of the housing. Install the strainer for ease of access and element removal. Use adequate piping supports to avoid over- stressing strainer fittings. Add isolation valves downstream and/or upstream of the strainer to allow opening and manual cleaning of the element without draining the entire line.
To monitor plugging of the strainer during operation, pressure gauges may be installed on both sides of the strainer to measure differential pressure. When the strainer has been cleaned, it will have the minimum differential pressure at the operating flow rate. If the strainer starts to get plugged, this can be detected by an increase in the differential pressure. In addition, electronic signals from differential pressure sensors may be included to automatically detect and alarm the control system.
